A Control Method for Linear Permanent Magnet Electric Submersible Pumps in a Modified Integrated Drive-Motor System Conference Paper uri icon

abstract

  • © 2017 IEEE. Electric Submersible Pumps are a widespread industrial solution for artificial lift applications in oil industries. Linear motors are becoming more popular as they are applied for new applications in various fields. Integrated Drive-Motor technology shows many promising advantages. In this paper, a system which combines these three technologies for marginal oil wells application is discussed. This system is intended to overcome some of the sucker rod pump limitations. A modified configuration for Linear Electric Submersible Pumps used in an Integrated Drive-Motor system is presented. In this system, the rectifier is placed on the surface while the inverter is integrated with the motor downhole. The main contribution of this paper is a proposed variable speed control method of this modified system that does not require a long signal cable. In order to avoid the long signal cable, the DC bus voltage is used to control the motor speed under Vector Control scheme. Experimental result verified the effectiveness of the proposed control method.
